Same exit as you have but water exits about half way down into the square cup, there are exit slits at the bottom, the sponge is the square with a 1” hole in the middle so the exit pipe is half way down into the sponge.
The bubbles that leave the skimmer are mostly broken in the bubble trap, few can exit.
